TABLE OF CONTENTS
Nashville • Franklin • Brentwood
- Under-sink & tankless RO (dedicated faucet + optional fridge line)
- Filter/membrane replacement on a schedule you don't have to remember
- Zip-code coverage across Williamson & Davidson Counties
Note: Nashville's latest CCR shows moderately hard water (~100.5 mg/L avg)—a great case for RO at the kitchen and softening for the rest of the home.
WHAT IS REVERSE OSMOSIS—REALLY?
Reverse osmosis is a point-of-use (usually under-sink) system that uses pressure to push water through a semi-permeable membrane. The "good" stream (permeate) goes to your RO faucet (and fridge line, if plumbed); the "reject" stream (concentrate) carries away dissolved solids.
WHAT IT'S BUILT TO REDUCE
- Dissolved salts (TDS) & many metals/inorganics: Lead, copper, chromium, sodium, arsenic, fluoride, nitrate/nitrite. Confirm certified reduction claims on the model's performance data sheet.
- PFAS ("forever chemicals"): EPA identifies RO among Best Available Technologies (BATs) for reduction; choose a unit certified for PFAS reduction.
- Microorganisms: RO membranes can remove parasites, bacteria, and viruses (municipal water is already disinfected).
- Microplastics: Membrane processes including RO can substantially reduce microplastics in drinking water.
WHY NASHVILLE-AREA FAMILIES CHOOSE RO
Benefits you can feel and taste every day.
TASTE & ODOR
Lowers TDS and, with built-in carbon stages, improves chlorine/chloramine taste and odor so coffee, tea, and cooking taste clean.
LOW-TDS WATER
Great for ice clarity, kettles, and espresso. NSF/ANSI 58 baseline ≥75% TDS reduction for labeled systems.
PFAS PEACE OF MIND
RO is on EPA's short list of effective home treatments for PFAS (pick a unit with certified PFAS reduction).
LESS PLASTIC WASTE
Many families cut bottled-water purchases dramatically with home RO systems.
WHAT RO DOESN'T DO (AND HOW WE HANDLE IT)
CHLORINE PROTECTION
Free chlorine can damage thin-film RO membranes; quality systems include a carbon pre-filter ahead of the membrane.
WHOLE-HOME SCALE
RO is for a drinking line; to address spots/scale on glass, fixtures, or tankless heaters, pair filtration with softening/conditioning.
pH & MINERALS
RO lowers dissolved mineral content; low-mineral water can read slightly acidic from CO₂ absorption. EPA treats pH as a secondary (aesthetic) standard (typical 6.5–8.5). Add remineralization if you prefer the taste.

HERE ARE YOUR OPTIONS
Under-Sink RO (Most Common)
- •Clean drinking water at a dedicated faucet (and fridge, optional)
- •Tanked (storage for quick pours) or tankless (continuous production, compact)
- •We install air-gap faucet & code-compliant drain connections
- •When possible, we recommend WaterSense-labeled systems (NSF/ANSI 58 + efficiency disclosure; typical ≤2.3:1 waste-to-treated ratio)
Countertop RO
Good for renters/apartments. Countertop placement; no plumbing changes.
Whole-House RO
Niche solution (e.g., high-TDS well water) requiring storage and re-pressurization. We can design it if truly needed, but most families don't need whole-home RO.
HOW WE CONFIGURE A WILL'S FRIENDS RO (MIDDLE TN)
TEST & GOALS
Taste/odor, PFAS concerns, fluoride preferences, coffee/espresso needs, plumbing layout.
MEDIA STACK
Sediment → carbon (for chlorine/chloramine) → RO membrane → optional remineralization (for taste/pH).
EFFICIENCY & PERFORMANCE
Prefer models certified to NSF/ANSI 58; when possible, spec WaterSense-labeled systems to cut water waste without sacrificing performance.
CLEAN INSTALL
Air-gap faucet, tidy tubing, code-compliant drain connection, optional fridge line.
Maintenance Plan
Prefilters per schedule; membranes last multiple years when protected/maintained. We set reminders and handle service.
PRICING, INSTALL & WHAT TO EXPECT (MIDDLE TN)
Transparent Quote
Under-sink and tankless RO options with or without remineralization.
Clean Install
Air-gap faucet, tidy tubing, optional fridge line, professional drain connection.
